automation: ensure created are not owned as root

automation: ensure created are not owned as root

By default the container runs as the root user and since the source tree
is bind mounted into the container, any file is created and owned by the
root user which harms ergonomics when working outside of the container
environment. This maps the root user within the container to the uid of
the user outside of the container so files are not owned by root.
